In 2015,Muench, Falk; Juretzka, Benjamin; Narayan, Suman; Radetinac, Aldin; Flege, Stefan; Schaefer, Sandra; Stark, Robert W.; Ensinger, Wolfgang published 《Nano- and microstructured silver films synthesised by halide-assisted electroless plating》.New Journal of Chemistry published the findings.Category: alcohols-buliding-blocks The information in the text is summarized as follows:
Electroless Ag plating baths were modified with different amounts of chloride and bromide, and the effect on the deposition kinetics and the morphol. of the resulting Ag films was evaluated. The baths were based on Ag nitrate and tartrate as the metal source and the reducing agent. Ethylenediamine was used as the complexing agent to suppress Ag halide precipitation With increasing halide concentration, a reduction in the deposition rate and a decreased tendency towards three-dimensional nucleation was found. Bromide affected the plating reaction more strongly than chloride. The deposit morphologies range from coarse-grained, compact particle aggregates over bimodal structures composed of island-like microparticles and smaller particles of varying geometry to shape-controlled films dominated by plates with a triangular or hexagonal shape. The fabrication of Ag films of adjustable micro- and nanostructure is relevant for various applications such as heterogeneous catalysis, sensing and plasmonics. As an example for structural tailoring enabled by the outlined reaction system, the authors created a biomimetic, self-cleaning coating possessing a static contact angle of 165 ± 3° and a tilt angle of <3°. To this end, a hydrophobic metal surface was designed which exhibits a superimposed roughness on the micrometer and submicron scale. The former was defined by the Ag deposition, the latter by consecutive galvanic replacement. To achieve superhydrophobic properties, the metal surface was coated with an alkanethiol self-assembled monolayer. In the experiment, the researchers used Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Category: alcohols-buliding-blocks)
Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5) is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient. Category: alcohols-buliding-blocks As a Biuret reagent, it is used to measure the protein concentration. Furthermore, it is used as laxative and is also used in food industry.
